Ans- By selecting double click we can use any command (tool) more then one time.

Q14- Difference b/w geometrical and dimensional constraints?
Ans- Geometric constraint is a relationship that forces a limitation b/w one or more geometric elements.
Dimensional constraint is a constraint, whose value determines the geometric object measurement.

Q15- Expamd CAM/CAD/CAE/PLM/VPM/VPDM/CFD.
Ans- CAM- Computer aided Manufacturing
         CAD- Computer aided Designing
         CAE- Computer aided Engineering
        PLM- Product life cycle management
        VPDM-  Virtual product data management
         VPM-  Virtual product module
         CFD- Computational fluid dynamic.

Q16- What is difference between add and assembly in catia v5?
Ans-  Add is the Boolean operation which is used to add the material no matter whether it is positive feature or negative feature but assembly is the one which considers if it is positive feature it adds material and if it is negative feature it removes material

Note: Positive feature are the options used to add material like pad, shaft, rib, multi section solid..... etc
negative feature are the options used to removes material like pocket, groove, slot, remove multi section solid.....etc
